With the newly-enforced connection limits, the two production servers of the dashboard may be sometimes exceeding the connection limits. Adding them to the whitelist would be great.
For outreachdashboard.wmflabs.org, here's the data I have:
eth0 inet: 10.68.16.172
eth0 inet6: fe80::f816:3eff:fed4:13c2/64
public IP via dig TXT +short o-o.myaddr.l.google.com @ns1.google.com: 22.214.171.124
